The Xendi Kabu system was a star system close to a class 4 pulsar and a dichromic nebula in the Dorias Cluster.
In 2370, DaiMon Bok sent a probe towards the USS Enterprise-D from this system. Later, the Enterprise entered this system to investigate the matter further, encountering several other probes, and eventually, Bok's ship. (TNG: "Bloodlines")
According to the Star Trek: The Next Generation Companion (3rd ed., p. 294), the writers of "Bloodlines" intended this system to be the same as the Xendi Sabu system in "The Battle". The name was mistakenly changed in a late draft of the episode's script. Curiously, the closed captioning spells this system's name as "Xendi Sabu".
According to the script, this system's name was pronounced as "zen-dee KA-boo". [1]
